We study neutrinoless double beta decay (0νββ) mediated by non-interfering exchange of both light and heavy Majorana neutrinos, by taking into account recent calculations of nuclear matrix elements (NME) from various nuclear models. We put upper limits on the light and heavy neutrino contributions to 0νββ decay, using data from current experiments (KamLAND-Zen, EXO, GERDA, MAJORANA, and CUORE), and also evaluates the potential signals at a significance level greater than 3σ in future projects like nEXO, LEGEND, and CUPID.

Abstract
We study neutrinoless double beta decay (0νββ) mediated by non-interfering exchange of both light and heavy Majorana neutrinos, by taking into account recent calculations of nuclear matrix elements (NME) from various nuclear models. We put upper limits on the light and heavy neutrino contributions to 0νββ decay, using data from current experiments (KamLAND-Zen, EXO, GERDA, MAJORANA, and CUORE), and also evaluates the potential signals at a significance level greater than 3σ in future projects like nEXO, LEGEND, and CUPID.File in questo prodotto:
